About

I am Charin Modchang, a physicist and infectious disease modeler at the Department of Physics, Faculty of Science, Mahidol University, Thailand. My work sits at the intersection of physics, mathematics, computer science, and public health, with a central goal: to use quantitative models and AI to better understand, anticipate, and control infectious diseases. 

My research focuses on the transmission dynamics of infectious diseases, including directly transmitted infections (such as respiratory diseases), vector-borne diseases (such as dengue and other mosquito-borne infections), and zoonoses that can jump between animals and humans. 

I develop and analyze mathematical and computational models, from mechanistic models to AI-driven approaches, to explore how infections spread through populations and how interventions—vaccination, vector control, behavioral measures, or policy changes—can alter those dynamics over time and across regions. A substantial part of my work involves extracting insight from disease surveillance data, including both routine clinical reporting and wastewater-based epidemiology, to support data-informed decision-making, especially in low- and middle-income countries. 

Beyond research, I serve on the editorial boards of Scientific Reports, BMC Infectious Diseases, and PLOS Global Public Health, contributing to the peer-review process and helping shape the direction of work at the interface of quantitative science and public health. 

I am also deeply involved in teaching and mentoring, supervising students and early-career researchers who are interested in mathematical modeling, AI for health, and the physics of complex biological systems. I enjoy working with interdisciplinary teams—including clinicians, epidemiologists, public health officers, and data scientists—to tackle real-world problems using rigorous quantitative tools.
